The MCS NFS fileservers will be undergoing maintenance from 6AM CST December 27 to 6PM CST December 28.
We are moving home directories and our softenv environment to a new server during this window. This work
is being performed to provide performance improvements and more available space.
During this period you may not be able to logon to linux workstations, and many of our filesystems will
be marked readonly. The linux workstations, login and compute servers will be restarted at the completion
of this maintenance.

The new copier/printers are being installed today. We’re in the process of getting them set up. We’ll send an announcement with a link to instructions when everything’s all set and ready to go. You should be able to use the copy function now, but the rest will require a little time before it’s all online.Thanks!
This outage and upgrade is going ahead. The time frame is from noon until 5PM. Happy Thanksgiving!
The latest Zimbra release addresses a bug we’ve hit recently, and we’d like to roll it out quickly. As Thanksgiving weekend tends to be slow, this coming Saturday is the first choice. The outage would last around 5 hours (9AM to 1PM), and during the outage you couldn’t check or send mail, nor get to your calendar. No mail would be lost, it would simply queue up during the outage and be delivered after the upgrade is complete. These things tend to go smoothly.If this poses a problem for anyone, please let me know. Otherwise, we’ll send another announcement later this week making it official. Thanks!
All,The MCS account pages recently received an update. The next time you
login, you will notice a new look and some differences in the
organization of data. Some of our documentation may be out-of-date
regarding the new pages, but we are working to update all the relevant
info ASAP. Please send any questions/comments/suggestions to
The power work was completed ahead of schedule. Power is back to the building, but due to the coordination problems of shifting the schedule, we’re not changing it. (For instance, can’t turn on cooling to the datacenter until there’s sufficient load to cool.) Will be there around four. Building network is scheduled to come back at 7, I believe.
Please note this will affect all machines in the datacenter. Primary websites will stay up, as will cryptocard, database servers, mailing lists, and RT, as we have hosted those servers in another building. Compute servers, file servers, and clusters hosted in 240 will be down. The power will not return until 5PM on Sunday, at which point we can start turning things back on.
It’s time to conduct our User Feedback survey. (Well, past time, really, since it’s been over a year.)You can find the survey here: http://www.surveymonkey.com/s/KVTHY6Y (also linked off our blog (systemsblog.mcs.anl.gov), and the IT Wiki (mcs.anl.gov/help)). The survey is open until 10/31, and all answers are completely anonymous. I’ve simplified the questions somewhat and went a little more free-form with the answers. There are six questions in total. Thanks.
(earlier, blog only)> I’ve identified and replaced the failed server, and authentication is working again. We’ve got some NFS issues lingering that I’m tracking down that are preventing people from logging into the login servers. I’ll post another update once that’s taken care of. Update: NFS has been restored. Some machines may need a reboot. login2.mcs.anl.gov was rebooted in the process of debugging this. login1.mcs.anl.gov was done in by a combination of the service outage and a user job on the login node that ran the machine out of memory. login3 and login4 remained up.
Zimbra issues seem to have cleared up as soon as the authentication service was restored. This outage affected:
CELS Zimbra users
MCS LDAP/Kerberos authentications (including MCS Unix workstations)
MCS License servers. We will investigate why backup authentication methods did not help, as well as why CI Zimbra users were affected. Thanks for your patience.
